Air Conditioning Repair Tip: Why Change the Air Filter

An air conditioner needs annual maintenance, consisting of an inspection and tune-up, for it to run efficiently and effectively during the year. It takes the knowledge of an HVAC professional to perform maintenance, so you should seek out a maintenance program from a trusted contractor to handle this task for you each year.

You can take a few maintenance steps on your own. One of the most important is to regularly change the air filter on your air conditioner; you might need to do it as often as once a month during the summer. We’ll explain why this is such a crucial step. (If you don’t know the location of the air filter for your system, ask a repair technician.) If you need air conditioning repair in Bergen County, NJ because of air filter troubles, call on DB Heating & Cooling—any time of the day or night!

Why replacing the air filter is necessary

  • To prevent debris contamination: The air filter is located where the return air vent brings in air from inside the house to circulate through the AC. Dust, lint, pollen, dander, hair, and larger particles like gravel can come with this air. If these pollutants get inside the air conditioner’s cabinet, they will cause damage leading to inefficient operation and eventually repair needs. Dust can cause motors to run down and evaporator coils to ice over, while large contaminants can bend fan blades. If the air filter becomes too clogged with the objects it traps, it can develop damage that will allow the debris to get inside.
  • To maintain airflow: As the filter catches more debris, it will start to slow down the airflow into the air conditioner. A thick clog can choke off the flow to almost nothing. Even minor clogging will restrict flow enough that the AC will need to work harder, and this will cause a drain on power. You will notice a spike on your energy bills as the filter becomes congested.

A bit more on filter change frequency

According to the U.S. Department of Energy, you should change the filter every 1–3 months depending on the type of AC, where you live, the time of year, and how much you use the system. During the summer, when you run the air conditioner frequently, you should change the filter every month. During cooler seasons, you can lower the frequency, although make regular checks to see how fast the debris builds up.

Regular maintenance will help you with this task, since your technician will detect how quickly the filter clogs up. (Changing the filter is part of a maintenance visit.)
